CompactPrep Plasmid Midi Kit

For fast purification of up to 200 µg molecular biology grade plasmid DNA

Purification of up to 24 samples in <60 minutes

Low elution volumes for highly concentrated DNA

Bench-top processing with no need for large centrifuges

LyseBlue for optimum lysis and maximum DNA yield

CompactPrep Plasmid Kits provide fast spin column-based large-scale plasmid purification. Up to 24 samples can be processed in parallel in less than 60 minutes using a vacuum manifold (e.g., QIAvac 24 Plus). Handling of the samples is fast and easy. CompactPrep Plasmid Kits require use of a vacuum device (e.g., QIAvac 24 Plus). Note: CompactPrep Plasmid Kits do not contain QIAfilter Cartridges and require centrifugation for lysate clearing.
For optimal results it is recommended to use this product together with QIAvac 24 Plus.

Product Details

Microcentrifuge column format.

Low endotoxin levels.

Plasmid DNA was purified from 25 ml and 100 ml cultures of the indicated E. coli strains using the CompactPrep Plasmid Midi or Maxi Kit protocol. The endotoxin content of the purified plasmid DNA was determined using the Kinetic-QCL Kinetic Chromogenic Assay. The average endotoxin content is shown.

Maximum plasmid yields using LyseBlue

LyseBlue reagent is now also included in CompactPrep Kits ensuring high DNA yields. Using a simple visual identification system, LyseBlue reagent prevents common handling errors that lead to inefficient cell lysis and incomplete precipitation of SDS, cell debris, and genomic DNA. LyseBlue is optional and provided in a separate vial within the kit.

Principle

QIAGEN CompactPrep Plasmid Kits provide a novel method for fast large-scale plasmid preparation. The procedure is based on a nonchaotropic binding chemistry, reducing the total preparation volume to miniprep scale. All protocol steps after cell harvest can be performed at the bench using QIAfilter cartridges, a vacuum manifold, and a standard microcentrifuge. The unique kit chemistry and design of the CompactPrep column ensure large-scale plasmid prep yields using a spin column format.

Procedure

CompactPrep Plasmid Kits provide fast, large-scale, nonchaotropic silica-based plasmid DNA preparation. DNA binding and washing using a spin column on a vacuum manifold (e.g., QIAvac 24 Plus), and DNA elution, using a microcentrifuge, enables the entire plasmid purification process to take place at the bench.
